Kay Sievers d6c238503e misc: fix platform driver hotplug/coldplug
Since 43cc71eed1, the platform modalias is
prefixed with "platform:".  Add MODULE_ALIAS() to the hotpluggable 'misc'
platform drivers, to re-enable auto loading.

Carlos Corbacho 343c00422d acer-wmi: Rename mail LED correctly & remove hardcoded colour
The mail LED name for acer-wmi currently hardcodes in the colour as green.
This is wrong, since many of the newer laptops now come with an orange
LED, and we have no way of telling what colour is used on a given system.

Also, rename the mail LED to be inline with the current recommendations of
the LED class documentation.

Henrique de Moraes Holschuh cee47f5a32 ACPI: thinkpad-acpi: fix hotkey_get_tablet_mode
I used the wrong return convention on hotkey_get_tablet_mode(), breaking a lot

Fix it to return the status in the parameter-by-reference, and IO status on
the function return value.  Duh.

Sam Ravnborg 7560e38565 acer-wmi: fix section mismatch warnings
Fix following warnings:
WARNING: vmlinux.o(.text+0x672615): Section mismatch in reference from the function acer_platform_remove() to the function .exit.text:acer_backlight_exit()
WARNING: vmlinux.o(.devinit.text+0x1e859): Section mismatch in reference from the function acer_platform_probe() to the function .init.text:acer_led_init()
WARNING: vmlinux.o(.devinit.text+0x1e878): Section mismatch in reference from the function acer_platform_probe() to the function .init.text:acer_backlight_init()

Remove __exit annotation from acer_backlight_exit(). We cannot reference
a __exit annotated function from non __exit functions.

acer_led_init() and acer_backlight_init() where both annotated __init but
used from a __devinit function. This would result in an oops should
gcc drop their inlining and the module are hot plugged.

Fix by annotating acer_led_init() and acer_backlight_init() __devinit.

Henrique de Moraes Holschuh 6c231bd5eb ACPI: thinkpad-acpi: add tablet-mode reporting
A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the
existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the
X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is
tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is
set).

Add an attribute to report this information, "hotkey_tablet_mode".  This
attribute has poll()/select() support, and can be used along with EV_SW
SW_TABLET_MODE to hook userspace to tablet events.

Len Brown 4a507d93fa acer-wmi, tc1100-wmi: select ACPI_WMI
It is safe for these Kconfig entries to use select because
they select ACPI_WMI, which already has its dependencies
satisfied.  This makes Kconfig more user friendly, since
the user selects the driver they want and the dependency
is met for them.  Otherwise, the user would have to find
and enable ACPI_WMI to make enabling these drivers possible.
